8. The closed cut-off light Fu Biankuang assembly of claim 1, wherein the mounting top surface slopes toward a direction proximate the mounting bottom surface when extending rightward to the right end of the mounting top surface to form a first glue overflow prevention structure.

9. The closed cut-off light Fu Biankuang assembly of claim 1, wherein the closed cut-off photovoltaic bezel assembly is made by a cold roll forming process.

10. A closed cut-off photovoltaic bezel, comprising:

connecting the corner connector;

the closed cut-off light Fu Biankuang assembly of any one of claims 1-9, a plurality of adjacent closed cut-off light Fu Biankuang assemblies being assembled into the closed cut-off photovoltaic bezel by the connection angle code, two angles of the connection angle code being inserted into the support cavities of two adjacent closed cut-off photovoltaic bezel assemblies, respectively, for fixation.
